Why are all Domesticated cats basically the same size?

[Genduko]

as compared to domesticated dogs where you can get small dogs like a jack Russel and then you can get bigger ones like a labrador where as all domesticated cats are usually the same size.

Pretty much im asking why cant domesticated cats get as big as domesticated dogs

 

[kakashi owns all]

a large cat could be very deadly much more then dogs thats why

Simply because dogs show a larger genetic variation than cats and that's a scientific fact thus more variation means variable sizes for dogs and less for cats.

You basically answered your own question; They've been domesticated.

Also not all of them are the same sizes, they have pretty big ones, like Long cat;
